PURE STRUCTURE
- Pure VCO is a voltage-controlled oscillator that generates complex waveforms. The core wave can be morphed from sine to triangle and then is folded in a specific way to give harmonics without sharp edges in the folded waveform.
- A switch allows to use another type of folding that create unbalanced folding with different amplitudes in the resulting ripples. This creates different rich harmonics in a way that avoid aliasing.
- Thanks to its audio input, the module can also be used as a voltage-controlled wave folder that can add harmonics and distortion to the incoming signal in a very specific way.

TIMBRE STRUCTURE
- Timbre is a 4 modes VCF inspired by experiences on analysing, copying and modifying real hardware OTA VCFs.
- The filter is not based on VCV filter algorithms but developed with Vult (trans-compiler for high performance DSP, developed by Leonardo Laguna Ruiz).
- The algorithm offers non-linearity into the gain structure of the filter and a specific type of resonance. The resonance can also be “overloaded”, for a warm bass sound in low pass mode.
- As the development stage allowed to try several interesting sound path circuitry for the resonant feedback loop (linear, non-linear, clip), the module allows the user to do the same. The filter offers send and return in/out that bypasses the internal feedback loop and allows to modify it with sound effects or VCA to get voltage-controlled resonance.
- Another specific feature of this filter is the accent input that can be used for XoX bassline sequences.

AMPLITUDE STRUCTURE
Amplitude is made of two VCAs that offer voltage-controlled attenuation – inversion (called strength). The two VCAs outputs and an auxiliary input are sent to a mixer. The aux input has a dedicated attenuator. It also includes a led quadrant on each VCA :
- Vertical position displays the phase and amplitude of the incoming signal (positive or negative)
- Horizontal position displays the phase and amplitude of the control signal (strength).
- Like on the “timbre VCF” there is an accent input for x0x style sequences.
- This module is more than a VCA and can be used as a mixer, attenuator, inverter, VC polariser,…

MODULATIONS
TWIN QUARTET STRUCTURE
- Twin Quartet is a dual quadratic LFO. It can be used for rotary effect, Shepard tones, stereo/ quadraphonic control.
- The core of the module has two separated LFO with a selectable waveform for each. They are linked by their frequencies.
- The left LFO (master) has a fully controllable frequency, while the frequency of the right LFO (slave) uses a multiple of the master LFO from /8 to x8).
- Each LFO has 4 phase state outputs. The phase (X) can be set by the user or by CV control, from 0° to 90° between each output.

RELIEF STRUCTURE
- Relief is a dual complex envelope generator with level detector and gate delay. It can be used for bouncy effect and complex triggering.
- Each of the envelope generator has two classic stages: attack and decay, both CV controllable.
- Once the cycle is completed, there will be a trigger emitted out of the end of cycle output. This signal can be used to trigger any other event. It can be used to trigger the next envelope for a complex 4 stages envelope. It can also be self-patched to the gate input to create a lfo.
- The level detector will create a gate signal whenever the envelope signal is above a defined threshold.
- Relief also features a gate delay that can be used to convert a trigger into a gate or to postpone it. The output of the gate delay can trigger the 2nd envelope by using the toggle switch.

PROCESSORS
FOLLOWER STRUCTURE
- The Hora Follower creates an envelope signal that follows the general amplitude of an audio source.
- The speed of the follower (decay) can be set by the user.
- The module also offers a gate or trigger input that opens whenever the envelope passes over a defined threshold.

SPECTRAL CONCEPT
- The spectral processor is a 16-channel bandpass filter, it can work as a real-time performance filter, a programmable compound equaliser and even as a spectrum transferring vocoder.
- It shares the same interface as the Buchla 296e and offers the same features such as Xfer or voltage-controlled A-B morphing.
FILTERS
MULTI BAND FILTERS
- The spectral processor splits the incoming signal in 16 separated fixed bandpass filter with general Q control.
- Each band can be attenuated by its touch pad or by its CV input. Each of them can generate a CV signal . thanks to its envelope follower with editable decay.
- When one input is connected, the module will process the sound through the 16 filter bands,
- when both inputs are connected, the odd input will be sent to the odd bands and the even input will feed the even bands as two parallel sound paths.
- The audio level of each band can be monitored with the OUT button.
PROGRAM
PROGRAMMING A B
- The band level can be set by the touch pads and then saved in two different states A and B.
- The two states can be accessed and edited with the A and B button.
- A continuous fading between the two states can be programmed with the A/B knob or CV control.
- This morphing can be monitored with the PROG button.
SPECTRAL BAND CONTROL
BAND VCA CV INPUT
In addition to the touch pad control and the program fea- ture, the level of each band can be controlled by a voltage signal with the input under each touch pad. a
BAND ENVELOPE FOLLOWER CV OUTPUT
- Each band has its own envelope follower and will output a CV signal depending on the audio level received in the filter (jack output above each touch pad). A
- The amplitude of the CV can be edited with the touchpad using the ENV button.
- The decay of the CV can be edited with the touchpad using the DEC button. B
XFER
The XFER sends the envelope out of a band to the next band’s VCA CV input. It allows two internal routing options:
- EO: sending every even band env output to the next odd band vea input
- O>E: sending every odd band env output to the next even band vca input
- EXT: no internal routing.
- This is especially useful when two different sources are fed to the odd and even bands to create cross modulation ampli- tude, vocoder effects, applying the amplitude of a signal to another sound source, …
